The Respiratory System:
§
includes lungs, trachea (windpipe),
bronchial tubes, alveoli;

takes in air to get Oxygen, or O2
so cells can get energy from food;

absorbs O2 across the thin walls of
the alveoli into capillaries (tiny blood vessels), so the
circulatory system can carry O2 to all cells;
§
exhales Carbon Dioxide, CO2,
a waste product from the body's breakdown of food.
